SPECIFICATION forming part of Letters Patent No. 232,867, dated October5, 1880.

Application filed February 14, 1880. I

Gang-Plow; and I do hereby declare that the following is a specificationthereof.

My invention relates to gang-plows which are arranged upon wheels; andthe objects of o my improvements are, first, to provide a frame pivotedto the axle at one side and raised by a lever on the other in aguide-hanger, to level the frame 5 second, to provide a rock-shaft setdiagonally upon the frame, with rigid arms and links to both lever andplow beams. These objects I obtain by the mechanism shown in thedrawings, in which- Figure 1 is a perspectixe view of the entiregang-plow, a portion of one of the carriagewheels being broken out inorder to expose parts behind it. Fig. 2 is a vertical cross-seetion ofthe same, and Fig. 3 is a longitudinal section of a portion of thegang-plow detached from the axle and wheels.

Similar letters refer to similar parts throughout all the views.

The frame A consists of a tongue portion, a, and two rear-extending sidebeams, a a united at front by a widened rear portion of the tongueproper. On the inner side of the beams to a plow-beams B B are arranged,and these beams are pivoted to the frame-beams near their front ends, asindicated at c, and they are confined against sidewise movement in rearof the pivots c by strap-loopscl fastened to the inner sides of theframe-beams.

The plow-beams are of different lengths, and their rear portions arecurved to form standards, and on the curved portions plows C O areplaced and fastened in the usual manner. The plows O 0 respectivelyconsist of an ordinary mold-board, e, and a eolter, 0, which serves theoffices of landside and colter. The colter e conforms on its lower edgeto the landside edge of the mold-board, and extends from the point ofthe plow to the inner top edge of the mold-board, being quite deep,standing vertical, and having its upper edge curved in form of the bellyof a fish, and sharp. This colter serves for cutting brush and otherobstacles, and it insures the falling of the sod or furrow-slice in theproper direction away from the landside, and while it dispenses with theordinary landside it prevents choking of the plow with weeds and trash.

D is a rock-shaft placed in upright bearings f f of the frame-beams a asaid bearings being set one in rear of the other on the respective beamsa (o in order that the rock-shaft shall lie diagonally across the frameA, and thereby have one of its ends stand nearer to the middle of thelong plow-beam B than its other end, and by this means avoid theinconvenience arising from the employment of arms of unequal lengths onthe rock-shaft for raising and lowering the plow-beams.

The rock-shaft D has two lever-arms, E E, of equal length, attached toit, and to these arms link-bars F F are pivoted, to the rear ends ofwhich the plow-beams are connected by loops slipped upon the beams andpivoted to the linkbars, as shown.

G is a hand-lever, connected to the rockshaft by means of a toggle-jointlever, g g, said hand-lever being piroted to a stand, h, of the frame A,and provided with a locking tooth or catch, 2', and a pressure-spring,j, as shown.

H is a notched are fastened to the frame A on one side of the standardof the attendants seat I, with which the levers G and L are held inengagement by the spring j and .a spring, g

By the combination of the diagonal rookshaft, hand-lever, and theintermediate togglelevers, g F, and the locking devices, the gang ofplows can be very easily and conveniently raised and lowered by theattendant from his seat on the carriage.

The axle J is pivoted near one of its ends to a hanger, a, of the frameA by means of a longitudinal pivot, said axle being left free to riseand fall at its other end, and an oblong vertical loop or hanger, a,guiding and controlling it at its free end. The loop a is suspended fromthe under side of the frame A, and the axle is passed through it, asshown in the drawings.

To the axle, near its free end, another handlever, L, is connected bymeans of a link-bar, p, which is pivoted to a bracket, 1), of the axle,and to the short end of the angular hand-lever L, as shown. The leverserves to lower the gang of plows and frame together when it is desiredto adjust the gang-plow for operating with one wheel running in thefurrow and the other on the land.

Both of the hand-levers are in close relation to the attendants seat I,and one are answers for both levers; and the attendant While sittingupou his seat can either raise or lower the plows, or raise or lower oneof the wheels or the frame, the latter operations being ef- 1o fected bymoving the frame or the axle on the longitudinal pivot of the hanger n,while its free end is guided by the loop.

What I claim as my invention, and desire to secure by Letters Patent,is-

l. The frame A, pivoted to the axle at n, and provided with the hanger aand lever L, in combination with the diagonal rock-shaft D, with rigidarms E g, lever G, and connecting-links, and plow-beams B B,substantially as shown and described.

2. The frame A, in combination with two or more independently-pivotedplow-beams, B B, of unequal length, said beams being pivoted to theinner sides of the beams a 0!. of the frame, and confined by oblongloops, as at c and d, and occupying a position above the axle, and alsobeing connected with a diagonal rock-shaft, D, and to a hand-lever, G,by devices F E and gg, substantiallyin the manner and for the purposedescribed.
